Abstract
In the foundation structure of a reactor containment vessel, a lower foundation plate provided on a ground, an upper foundation plate provided over the lower foundation plate, a base isolation device inserted between the upper foundation plate and the lower foundation plate, and a reactor containment vessel provided on the upper foundation plate are provided. The ends of reverse U-shaped tendons serving as the lower structures of the reactor containment vessel are fixed to the lower surface of the upper foundation plate through the upper foundation plate, which makes it possible to simplify a structure and reduce a construction cost.
